HELP!!! Fish disappearing

Guys,
Need help. In the last two days I've have an ocellaris clown and a six line wrasse go missing. I did hear clicking the other night. Is it as I fear - mantis shrimp?? I only have a pair of ocellaris clown, royal dottyback and yellow tang in the tank now.

Thanks
Neil
 
3 clowns would need a pretty large tank. one of them would end up dead eventually in a not big enough tank. clowns, sixline wrasse, dottyback, tang are all somewhat aggressive. how big is your tank?
 
Do six line wrasse bury themselves like a lot of other wrasse? I've heard of wrasse's burying themselves for a couple weeks with no sign of them (probably only coming out at night in most cases)
 
I have had a few unexplained absenses. Between the hermits and the starfish, I dont think I will ever see any proof. I dont think you have a mantis but to your point I hear clicking at night from time to time.
 
Mantis are less common than pistol shrimp but a remote possibility. Be careful about sticking your hands into your tank without gloves.
 
I forgot to mention my clowns are still only really small, males that is, so didn't think they will kill each other. My wrasse has never hid in the tank, hopefully this is the case though. Thanks for the replies.
 
Have you checked your overflow? I've had 2 clowns jump into mine.

+1 - similar thing happened to me.

Do you have turbo snails in the tank? Mine have made clicking noises from their shell hitting the class as they try to dislodge something.

Do you have any type of cover or netting on top of the tank? The fish may be jumping out to carpet surf.
 
i have had the same issue as of late. Two fish gone missing without a trace in three days. I have a picasso clown and had a mandarin goby that was healthy and eating and then disapeared on Monday after work. I replaced him last night with a yellow coris wrasse and after drip acclimating him for over an hour i placed him in the tank. I went for Chinese came back a half hour later....gone! I checked each rock individually and in the sand bed and no trace of anything. The only variable has been a newly aquired piece of fiji rock (week ago) that i bought at the LFS that had some nice polyps on it. The rock is beautiful but has numerous little crevices and tunnel like holes in it. i am thinking i got a hitch hiker. The Mandarin as most of you know hovers and the wrasse was also hovering and staying close to the rocks when i first put him in. I have standard clean up crew with hermits and snails although two of my hermits have grown rather large (shell is about the size of a quarter).

I plan to isolate that rock into another container I have with a power head and heater all by it self and let it sit for a day or two and then bait a trap and see if catch anything. Gonna set up the go pro under the water as well to post videos in case I do get anything. Has anyone tried this approach with success?

The first time the clown went missing I found him in the sump below however this time there is no trace of the clown or the 6 bar wrasse. Two fish in two days literally vanished without a trace.

when i added my yellow coris wrasse, he stayed hidden for 2 months. MONTHS! i got a couple of fleeting glimpses of him over that time. he finally came out of hiding about 3 weeks ago and he's out all the time now. you should never go digging in the sand for a wrasse. doing that will only stress him out more.
 
Worst case you got a bobbit worm... ugly but amazing creatures

Based on what i have been reading on those worms and what I have experienced that is what I think. i removed the piece of live rock from the tank based on my assumption that anything that has avoided that rock and is still alive. The wrasse and my mandarin were both frequent and fond of that rock since i put them in the tank. I set up a quarantine tank and hoping i trap it "if" i can. Any other ideas besides demolishing the rock looking for what ever it is?
 
THANK YOU inetmug!!! I was concerned that there was no answer to where my fish went. I've seen this bloody thing in the tank a few times and thoughts nothing of him. Jut thought it was some harmless centipede and too slow to do any damage. Funnily enough I haven't seen him for a while until the day after my fish went missing. Now how do I catch him????
